Who files this form

Arizona Form 335-I is for individual shareholders claiming a credit for their pro rata share of an S corporation’s qualified contributions to school tuition organizations. The 2025 form also provides space to claim available credit carryovers from 2020 through 2024.

What you'll need

Have the following information ready to complete the form:

• Your name as shown on your Arizona return and your Social Security number. For a joint return, include your spouse’s name and Social Security number.
• Each S corporation’s name and EIN.
• The names of the school tuition organizations and their credit approval numbers.
• Your pro rata share of qualified contributions from each S corporation.
• For any carryovers from 2020 through 2024, the original credit amount and the amount previously used.

Include a separate Part 1 for each additional S corporation. If you need more room to list school tuition organizations, include an additional schedule with the credit form.

How to file

Include Form 335-I with your return.

1. Complete Part 1 with the S corporation and school tuition organization information. Enter your share of qualified contributions on line 11.
2. On line 12, enter the amount from line 11. If you have more than one S corporation, total the line 11 amounts from all Part 1 schedules.
3. In Part 3, subtract previously used credit from the original credit for each listed year. Add the available carryovers on line 18.
4. In Part 4, enter the current-year credit on line 19, the available carryover on line 20, and their total on line 21.
5. Transfer lines 19, 20, and 21 to columns (a), (b), and (c), respectively, on the applicable form:

• If you did not make the Small Business Income election: Arizona Form 301, Part 1, line 12.
• If you made the Small Business Income election: Arizona Form 301-SBI, Part 1, line 8.

Common mistakes

• Leaving Form 335-I out of your return. The form says to include it with your return.
• Claiming shares from multiple S corporations without checking the box in Part 1 or including a separate Part 1 for each additional S corporation.
• Leaving out school tuition organizations because the form runs out of space. Include an additional schedule when needed.
